Chevrolet S-10 Repair Question
Mileage: No information provided.
Too Much Fuel
Answer
unplug all injectors and pull the plugs so the engine can dry out inside.Do a compression test. If it bent all valves and broke the head that bad, did you do anything about the rods and pistons?
i had the cylinder heads checked nothing was wrong with them thankfully and the rods are new there is pefect compression i didnt see myself but was told by a mechanic buddy who tested them.
double check all engine and chassis grounds, sounds like you might have missed one.
took me a couple days but i checked all grounds and all connections to make sure all of them are tight i evean unbolted and sanded the connections and put electrical grease on them to make sure of a good connection still havein same problem not sure whats goin wrong.
See if your mechanic buddy has a scanner. Need to see what sensor is telling the PCM that it needs more fuel. Test resistance across the injectors. Try unplugging the TPS and MAP one at a time and see if it still does it
